PIPE-JOINT COPLING.

Specification of Letters Patent.

Patented May 25, 1909.

Application filed December 21, 1908. Serial No. 468,440.

, To all whom 'it may concern:

Be it known that I, HUGH BAYARD HODGE, a citizen of the' United States, residing in the city and county of Philadelphia, State vof Pennsylvania, haveinvented a new and useful Pipe-Joint Coupling, of which the following is a specification.

It has heretofore been proposed in the manufacture of water pipe, to employ riveted sections of cement lined pipewherein the jacket does not go out to the ends, in conjunction with couplings wherein cemented joints are employed, in which case it takes from three to. four weeks after the 'oint is made before the cement is sufficiently hard to enable water to be-put into the mains,l

which is a very objectionable feature in practice.

To avoid the objections above noted I have devised the present invention wherein a bell and socket joint or bell ring is employed, one of the joint members having one of its extremities welded to the pipe section while its other extremity is deiiected outwardly and turned downwardly or inwardly. The other joint member has its outer extremity we ded to the pipe section proper and its inner portion deiiected downwardly then upwardly and over the 'uxtaposed terminal, and thence prolon ed and extended upwardly and downward? the space between the joints being packed with yarn or similar material which is held in place by a lead joint, the outer portion of the bell ring having the vouter jacket welded thereto, while over the bell ring, cement is placed after said lead joint is made, whereby it will be seen thatthe lead joint can be made at once, thus allowing the water to follow the laying of the pipe, so that pressure can be ut on the main at once, which is a vast improvement over the old style of joints hereinbefore referred to. A

To the above ends, my invention consists of a novel construction of pipe joint and its adjuncts as will be hereinafter particularly pointed out in the claims.

For the purpose of'illustrating my invention, 1 have shown in the accompanying drawings one form thereof which is at present referred by me, since the same has been found in practice to give satisfactory and -reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 re resents a side elevation of the exterior of a joint embodying my invention.

Fig. 2 represents a longitudinal section of Fig. 1. Fig. 3 represents a section on line -a;, Fig.

Similar numerals of reference indicate corresponding parts in the iigures.

Referring to the drawin 1 designates a section of pi e of su/ift'ab e material, interiorly lined wit ce s,eilt 2 or the like.

3 designates a/edliipling member which is welded or otherwise suitably secured at 4 to the pipe 2, the extremity of said coupling being deflected upwardly or outwardly at 5, thence interiorly at 6 and inwardly at 7, the lining of cement 2 being continued into the terminal of said coupling member, as will be understood from Fig. 2.-

8 designates the bell member of the joint, the outer end of the latter having the pipe 9 welded thereto, at-10, and both said pipe and member 8 being interiorly lined with the cement 11. interiorly as at v12, and thence extended out-v wardly as at 13, and then prolonged annularly as at 14, and thence enlarged as at 15 and thence contracted as at 16.

17 designates yarn which is suitably The member 8 is deiiected packed into the space' between the members 3 and 14, said yarn after being firmly packed or 'driven into position being retained in place by the lead joint 18, which can be made aty once, thus allowing the water to follow the laying of the pipe.

19 designates cement which is placed in position after the lead joint is made, the jacket 20 being welded to the coupling member 14 at about the point 21 and inclosing the cement 22, while the jacket 23 incloses the cement 24. The members 3 and 8 are vpreferably composed of wrought iron or medium steel, 'while the jackets 20 and 23 maybe composed of wrought iron or other suitable material.

It will be apparent from the foregoing that my new construction of pipe and joint possesses numerous advantages over the prior art since the various metallic. connections being welded there is initially, an absolutely water-tight pipe to start with and in my novel construction of joint, water can be let into the line at once before the pipe is covered up instead of having to wait from three to four weeks for the cement joint to harden which has heretofore iron on the male ring 3, and that w been a very serious objection to the practical use of all former joints in which cement had to -be used. By my novel construction I am also enabled to readil Arecalk the joints in case there is any sight leakage and furthermore, in my novel construction any person having any familiarity with the laying of cast iron pipe can lay this pipe equipped with my novel joint, whereas with a cement joint it is necessary to have specially trained men.

It will be apparent that the placing of the cement 19 around the joint after the lead 18 is poured acts as a protection to the exposed ile I have specified the yarn as being used at the point indicated by the reference nlumeral 17 and lead as being indicated b 18, and

-cementby 19, I do not desire to e limited to these materials as their equivalents may be employed without departing from the spirit of my invention.

Having thus describedmy invention, wha I claim .as new and desire to secure by Letters Patent, is:-'-

1. In a device of the character described, pipe sections terminatin in members juxtaposed to each other,`tI1e terminal of one of said members being inwardly dellected and the other of said members being also deflected inwardly, thence outwardly and then continued annularly, a packing disposed between said members, a metallic joint for holding said packing in place, and cement members.

2. In a device of the character described, pipe sections terminating in members juxtaposed to each other, said members being welded to the extremity -.of said sections, the terminal of one of said members being inwardly deflected and the other of said members bein also deflected inwardly, thence outwar y, and then continued annu- ,larly, a packing disposed between said members, a metallic joint for holding said packing in place, andcement placed over said joint and member rA 3. In a device of the character stated, cement lined pipe sections terminating in members juxtaposed to each other, the

terminal of one of said members being.

enlarged and lthen inwardly deflected, the

' other of said members being also deflected placed over said metallic joint and Y in place, and cement inclosing said metallic `oint. q J 4. Ina device of the character described, cement lined pipe sections terminatin in members welded thereto and having t eir ends juxtaposed to each other, cement inclosing said pipe sections and members, jackets inclosing said cement,;l one of said jackets being welded to one o'f said memers, the terminal of one of said members being enlarged and then inwardly deilected, the other of said members beingalso deilected inwardly, thence outwardly and thence continued annularly, a packing disposed between said members, a lead joint etween said members holding said packing in place, and cement inclosing said lead jointe 5. In a device of the character stated, an inner pipe section having a member welded thereto, a cement lining for said section and member, said member terminating in an enlarged and inwardly deflected terminal, a bell ring having a pi e section welded thereto, a cement lining or said section, said member having also an inwardly dellected portion, an annular extension, an enlarged portion and a terminal, a packing between the juxtaposed portions, a metallic joint holding said packing in place, and a cement lining surrounding said metallic joint and its adjuncts.

6. In a device of the character stated, an inner pipe section, havin a member welded thereto, a cement lining orA said section and member, said member terminating in an enlarged and inwardly dellected terminal, a bell ring having a pipe section welded thereto, a cement lining for said latter section, said ring having an inwardly deflected portion, an

annular extension, an enlarged portion and a terminal, a packing between the juxtaposed annular terminals, a metallic joint holding said packing in place, a cement lining surrounding said metallic joint and its adjuncts, cement surrounding said pipe sections, and

jackets surrounding said last-mentioned cement. v
